I have searched the forums and haven't found a similar issue. I have a 02 LS430 and on the driver side tailight the bottom left and top right lights don't work when the lights are on. I do get an alert on the dash indicating the lights are not functioning when I have my headlights on. I have tried to replace the bulbs but as soon as I replace them they burn out instantly. The harness and the bulb sockets look fine.

Anyone have any idea where I should begin with trouble shooting? I can capture a picture of the tailights and upload tomorrow.

If they keep burning out there must be a short somewhere in the line after the fuse or else the fuse would keep blowing. Electrical issues are the worst since they are not as easy to find. I would pull the trunk panels and have the wiring to see how it looks. Are you sure no moisture is getting into the tail light?

I too have question with tail lights. I have an 2004 LS430. I did not receive any fault messages. I only notice it when I was washing and waxing the car. My right tail light assembly has been hit and cracked. The light were out except for the turn signal which still works. I removed the assembly to inspect. It is crack and has water on the inside. There is a small circuit board on the inside. The board is all corroded. The part number on the board is P3407M. What is this work for?

If the housing is cracked I would just try to find one in the junkyard and replace the whole thing

I pulled the panels and checked the wiring and all looks good. I cleaned the bulb socket with a qtip and some alcohol. Plugged them in and all the lights on the rear of the car work now but I'm still getting the taillight our warning on the dash.

Is there anything I need to reset to get rid of this light?
